Finding Slope from a Graph
- K Redmond
The applet below describes how to find a slope given only the graph of a line. Recall the formula for finding slope, given two coordinate pairs and is . However, using this formula can be tedious when we can find it by just looking at a graph and counting the "rise over run" from a point on the left to a point on the right. Follow the directions of the applet below.
Keep in mind that in your own work, you can pick any two points that fit along the grid lines and fall on the actual line itself. Instead of dragging arrows around, you instead will be counting how far up or down, and how far to the right.
